Kill my application after finish

How to kill my application after call finish?

(i can see my app in HTC's phone, but i fini开发者_开发知识库shed that activity anyway)

There's really no need for this, Android automatically decides when to kill apps. However, you can, if you need to, kill it using:

Process.killProcess(Process.myPid());

this.finish() terminates my applications fine.

Have you looked in LogCat to see if anything is reported when you execute finish()??
